' To all whom t may concer/n: i

Be it known that` we, FRANK MESKER, CLnENoE E. SMITH, and JACOB Brno,` c-'itizens ofthe United States, residing .atzSt Louis, h/Iissouri7 have inventeda'certaiii new and useful lImprovement MetalWindow Constructions, of which the followingis a full,` clear, and. exact description, such as' will enableiQthers vskilled in'theart to which it appertains to 'make and use the same, 'reference being. had' to the accompanying drawings, forming part of this specification.

y Qur; inventionrelates generally to kmetallic for mounting 'th' swinging ventilator 'sec-i tion .upon certvaifn ofthe rails ofthe window sash andwhich mounting permitsthe ventilator to be readily inserted or removed from the sash, and, further, to provide im-.

provedfvl means for `producing weather and dust-tightI joints between ,the ventilator section and the framer of` the sashf i o' the foregoing and other objects in view, our, invention consists incertain novel features yof construction and arrangement .1 ,i of parts, hereinafter morenfully described eldg'f'clallrad 40 panying. drawings, in which,-

Figure 3 'is a perspective view ofa short portion of 4one of the vertical side rails of 'ther swinging ventilator frznne` and showing y the. arrangement. of thehliang'esthereon.

lReferring.by numerals to the accoi'npa'Iiy-y ing drawings which illustrate a practical embodiment of vourinvention, 1, l designate the upright ,side rails of the sash, Qthe ytop rail, 8l the bottom rail, 4 the inullions 'orJK intermediate upright rails`r andfthe intermediate transverse or horizontally disposed rails. Allof these railsare preferably constructed of ordinaryfcom'mercially rolled bars whichrrar'e 'substantially 'l'shape` in cross section and with the body portion of each rail or that portion including the laterally projecting flanges being substantially triangular in shape. f The rails making'up the sash are rigidly connected to feach other,` in any suitable manner7 for instance, by being welded,

l brazedfor by having interengagingportions forced together by pressure. v

Cil

The substantially triangular .por-. y

tions 6 vvvliicli include the lateral anges 7 ofthe rails l, 2, 3, 4 and are disposed on the oiiter'face ofthe sash while the webs `8 are disposed on the inner face of thesash.

Thel angesv? serve asv supportsffor 'the j,

panes` of. 'glass used in the window, said panes being secured to said anges in any suitable manner, preferablyfwith putty kor cement i t c A One oi' more of the mullions llandtransrvioo versje railsy arev remmradV vfr oi'n the central portion ofthe sash to form `-a ventilator opening, and to wprovide. bearin 's' Vfor the ventilator that'occupies this opening, brackets constructed fromk short sections of cal position, act as sealing 17 which, when the ventilator is "posed immediately angle bars are secured in any suitable manner to the inner faces of the webs 8 of the mullions 4 that are disposed immediately to the sides of said ventilator opening. Each of these brackets has one leg or flange 9a secured directly to the web portion 8 of one of the mullloiis and the other leg or flange 9b projects inwardly from the web of the mullion that is toward the vertical section of the ventilator opening. (See Figs. 4 and 8.) The upper edges 10 of the inwardly projecting legs 9b of these brackets constitute bearings upon which the ventilator frame rocks during its swinging movements.

The ventilator frame comprises a pair of lupright side rails 11, a top rail 12, bottom rail 13, one or more upright intermediate rails or mullions 14, and one or more intermediate transverse rails 15. The rails 12, 13. 14, and 15 are preferably formed from conn-l n iercially rolled bars that are substantially 'l-shape in cross section while the upright side rails 11 are constructed from rolled metal bars that are substantially channelshape in cross section with certain of their lateral flanges cut away or mutilated. The

-shaped upright side rails of the ventilator frame are cut away so that certain of the flanges on the upper part of the inside and ony the lower part of the outside remain. These remaining flanges of the Vmutilated rails 'when the ventilator frame is in a vertim'embers and prevent the movement of said ventilator fra-me laterally and vertically, but allow it to e swung open to an angle of ninety degrees (90). where horizontal and lateral movement is prevented by the engagement between the mutilated flanges. (See Fig. 8.) lVhen the frame is in a position approximately half-way between these extreme and locked positions, the ventilator frame may be removed fi'om the sash by raising it out of engagement with the fulcrum flanges of the fixed frame. Each upright side` rail 11 coinprises a web or body portion 16, and formed integral with the outer edge of the lower portion thereof is an outwardly presented flange closed, lies immediately against the outer edgesr of the lower portions of the mullions that are disto the sides of the ventilator opening.

Formed integral with the inner edges of the upper portions of the webs 16 are outwardly presentedflanges 18 which, when the ventilator is closed, lie immediately against the edges of the upper portions of the mullions that are disposed immediately to the sides ofthe ventilator opening. (See Figs. 6 and 7.)

Then the ventilator frame is properly positioned in the sash, the lower edges 18a of the flanges 18 rest directly upon the upper edges 10 of the inwardly presented flanges of' the brackets 9, and thus the ventilator frame has broad and substantial bearings during its swinging movements.

Formed integral with and projecting outwardly from the web 16 of each upright rail 11 and arranged intermediate of its edges a vertically disposed rib or flange 19, thc lower end of which terminates in a plane shortly below the lower end of flange 1S and when the ventilator is closed, the inner face of this flange lies immediately adjacent to the outer face 'of the corresponding flange 7 on the adjacent mullion. (See F ig. 6.)

Formed integral with the inner face of the web 16 of each side rail 11 is an inwardly presented flange 2O which performs the functions of a pane supporting flange, said pane being held in place by putty orthe like, as illustrated in Figures 6 and 7.

The rails forming the ventilator frame are securedto each other in any suitable manner,

either by brazing, welding or by having inteiengaging parts upset by pressure to such a degree as to provide a. firm and substantial connection. During the swinging movenient of the ventilator, the lower edges of the flanges 18 bear directly upon the upper edges 10 of the brackets 9, thereby enabling said ventilator to rock or swing freely from one position to another andr when closed, the flanges 17, 18 and 19 on the upright side members of the ventilator frame cooperate with the inner and outer edges and the inwardly presented anges 7 of the adjacent mullions to form weather and dust tight joints between the ventilator frame and sash.

Our improved Ventilating sash is comparatively simple, strong and durable, is c apable of being easily and economically produced, is constructed wholly of commercially rolled shapes which are readily obtainable in the op'en market, and the only rivets or like fastening devices utilized in the complete construction are those requiredv for securing the angle brackets 9 to the mullions of the sash, and which brackets serve as bearings for the swinging ventilator. j

Obviously minor changes in the details of construction may be made by those skilled in the art, without departing from the spirit of our invention, the scope of which is set forth in theV appended claims.

We claim as our invention:

1. In a metallic window construction, a metal sash, a ventilator o-pening therein, an

inwardly extending flange on the inner facey of said sash, terminating in an upwardly facing edge intermediate the top and bottom of the ventilator opening, a ventilator frame, an outwardly extending flange on the inner yface of said frame, terminating in a downwardly facing edge which is normally in substantial alignment with and resting upon the edge of said sash flange, said flangesy thereby cooperating as ,hinged membersfor swinging said frame in said sash. j

engaging the inner and outerkjfaoes respec-` tively of the sash, the inner flanges terminating in downwardly facing edges supported 0n the upwardly facing edges' of said sash" flanges and pivoted thereon for swinging 15 said frame in said sash. Y

In testimony whereof we hereunto aix lour signatures this seventh day of May, 1920. i
